[FIX] sale_timesheet: Traceback when launching tests from sale_timesheet module

When launching in an empty db the following command:

 ./odoo-bin --addons-path=../enterprise/,addons --db-filter=11ent -d 11ent -i sale_timesheet --test-enable --stop-after-init

it raised a traceback because no sale journal was defined.
